The England defender, who was recently stripped of the nation’s captaincy due to the ongoing race scandal, has been missing in action for Andre Villas Boas’ men for heir last Premier League and Champions League games, due to colliding with a goalpost against Portsmouth in January.
The veteran centre half has revealed that the operation, which took place last week, was a success, and that he should be back in four to six weeks.
“The operation went well and I’m feeling really good,” he told The Sun.
“The surgeon has shaved off a bit of bone in my right knee that was rubbing and causing a lot of swelling.
“We’re all confident the operation has solved the problem and it is looking good for a quick return.
“The medical staff say four to six weeks before I can play again. But, hopefully, it might be sooner.
“I’ll definitely be back before the end of the season to help the team in the Premier League run-in and for the Euros,” he confirmed.
